Ask Question block fails in Panels

(Not sure if this is a Panels or Ask Question issue. I have cross-posted. Delete if posted wrongly here -- and forgive me, I hope..)

When I add the Ask Question block into a region in Panels 3x, I get an error when I click "Finish." It says "an error occurred while attempting to process /panels/ajax/ etc. You can see the full error message by clicking on the attachment, which contains two screen prints. The first demonstrates how two other FAQ blocks worked fine.

I did theme the Ask Questions node/add by using themekey module. Other than that, all permissions are granted up to and including anonymous. I have checked and rechecked.

I did find it interesting that the url being processed referred to /faq_ask_1 / form while when I look at the blocks page I see it listed at faq_ask/1 (see: /block/configure/faq_ask/1 )

POSTSCRIPT:

While I was not able to click Finish when attempting to insert the Ask block, what's very wierd is that after I closed the pane and was back on the content page, I clicked Save and ..... lo and behold...... now I can ONLY view the Ask Faq form when I click on either Preview or on Edit Content!

How is that for strange????
